AD7190 adc equivalent, 4.8 khz ultra-low noise 24-bit sigma-delta adc.
RMS Noise: 7 nV @ 4.7 Hz (gain = 128) 16.5 noise free bits @ 2.4 kHz (gain = 128) Up to 23 noise free bits (gain = 1) Offset drift: 5 nV/°C Gain drift: 2 ppm/°C Specified.
It contains a low noise, 24bit ∑-∆ ADC. The on-chip low noise gain stage means that signals of small amplitude can be i.
